Gravity breaking hammer
The gravity breaking hammer comprises a hammer body shell, one side of the hammer body shell is fixedly connected with a middle cylinder body, and an opening is formed in the other side of the hammer body shell; the middle cylinder body is provided with a high-pressure energy accumulator and a reversing valve, a nitrogen chamber is arranged at the tail part, a slide way frame is arranged in the hammer body shell, a gravity piston is arranged in the slide way frame, a piston rod is connected with the gravity piston, and a drill rod extends outwards through an opening; the middle cylinder body lifts the piston rod to the rear body nitrogen chamber, the reversing valve performs valve element reversing through high-pressure oil, the piston rod of the nitrogen chamber drives the gravity piston to impact the drill rod, and the crushing action is completed. The gravity piston is additionally arranged between the piston rod and the drill rod, so that the impact force of the piston rod does not directly act on the drill rod, and the risk that the piston rod and the middle cylinder are strained is reduced. And the impact force is increased.
本发明提供了一种重力破碎锤，包括锤体外壳，锤体外壳一侧与中缸体固定连接，另一侧设开口；所述中缸体设高压蓄能器、换向阀，尾部设氮气室，所述锤体外壳内设滑道框，所述滑道框内设重力活塞，活塞杆与重力活塞连接，钎杆通过开口向外伸出；中缸体提升活塞杆至后体氮气室，换向阀将通过高压油进行阀芯换向，氮气室活塞杆带动重力活塞对钎杆进行冲击，完成破碎动作。本申请通过在活塞杆与钎杆之间增设重力活塞，使活塞杆的冲击力不直接作用于钎杆，降低活塞杆与中缸被拉伤的风险。并且增加冲击力。
